补充资料：卷边弯曲级进模设计
郑州工业高等专科学校(河南郑州 450007) 杨宗田
[摘要] 详细介绍了卷边、弯曲邪恶进模结构设计要点。
关键词 卷边 弯曲 级进模设计
l 产品结构分析
如图1所示产品结构图，材料为SECC，厚度为1mm，零件要求卷边，并且弯曲角度为65度。
2 排样设计
依产品结构，模具结构采用级进模结构，排样图如图2所示。排样间隙为0，其冲压工艺为：①冲孔；②修整；③首次弯曲；④卷边；⑤二次弯曲；⑥切断和最后整形。其中卷边和弯曲均分二次完成。
3 模具结构
(1)卷边工艺分二次完成，模具结构如图3a首次弯曲和图3b卷边。由于模具结构较详细，此处不再叙述。
(2)65度角弯曲分两次，第一次弯成90度，模具结构如图3c所示；第二次弯曲成65度(图4a、b所示)，模具结构及工作过程如图4所示，其模具结构很清楚，其工作过程不在叙述。
